[Setup]: AppName
Description:
This required directive specifies the name of the application being installed. Do not include the version number, as that is defined by the AppVersion and/or AppVerName directives. AppName is displayed throughout the Setup program and uninstaller in window titles, wizard pages, and dialog boxes. The value may include constants.
The value of this directive is also used as the default value for the AppId, VersionInfoDescription, and VersionInfoProductName directives if those are not specified.
Example:
AppName=My Program
